Alamut Valley
Located between the dry plains of Qazvin and the forested hills of Mazandaran Province, the Alamut Valley rewards those who spend some time hiking through it. You’ll twist and turn through the sandstone cliffs while passing sleepy towns along the way and perhaps a shepherd or two who’ve brought their flocks to graze. Otherwise, you’ll bask in isolation before coming upon the ruins of the Alamut Castle, otherwise known as the Castle of Assassins. It may be a far cry from the castle you have in mind, but the intriguing backstory and view from above promise to be worth your while.
